1986 Map of Ana River

USGS Topo · Published 1986

About this map

Summer Lake State Wildlife Area dominates this arid landscape at the northern edge of the Summer Lake basin, where managed water systems meet the high desert. The hydrological infrastructure is central to the area's utility, featuring the Ana Reservoir, a prominent Canal, and various levees that redirect the Ana River. This 1980s-era survey highlights the tension between the wet marshes of Schoolhouse Lake and the surrounding desert features like Alkali Flat and shifting Sand Dunes. For the local historian, the map preserves the location of established ranching outposts such as Thousand Springs Ranch, River Ranch, and the Carlon Ranch. Isolated landmarks like The Rosebud and the Lost Cabin provide specific points of interest for those studying the human footprint in this sparsely populated region of Lake County.
